Re: Westerbeke - no start post inj. pump rebuild.

All good theories. But doesn't explain why it won't fire on WD40.

How about this... All symptoms point to loss of compression. What if the shop gave me the wrong copper washers that go around the nozzle nut on the injectors. That could explain weak to no compression in all 4 cyls. Shooting some soapy water around the base of the injectors and cranking should lead to bubbles if air is escaping at the base of each.

I'll have to check with my T37 forum and see if our injectors actually had those think copper washers. That's the only thing I didn't take a picture of as I broke things down. The injectors were and afterthought and didn't seem very complex so I just popped them out and delivered them to the shop. Can't recall what was on them when I popped them out. They do have that crushable heat shield at the tip.
